Devices, of which the following sy ;-=My.inventionfrelates tdpot asv in e POLS O f'A various lsizes', aintfis liirl'ily flicieii in'usef. r. 1 Other vobjects will appear liereinaft The invention consists iii the coiiibinatioi "`and"arran einents of;partsliere'iiiafte"i de scribedan claimed. 'TheV invention will be l) Fig. l'is a vertical sectional viei of -i vdevice mounted in an operative position on, a potg",y F1gL2'is a'plan view partly in 'section miv line 2f-2 of Fig. 1, the cover'rplate `heilig partly broken :nvay;" Fig. 3 is a sectional View on line -3--3 of- Fig. 1';

' F ig. 5 is a verticalsection talccir on; line 5,5ofF1g.1.

I have shown my invention-in connection? witli an ordinary poter kettle 10 having its upper edge turned outward `forming a curved bead 11 on ivliicli the device is snpporled and iirmly clamped as' shown. lliis device contains, in :i generalway, means for supporting and clamping the device on a pot and which means is adjustable to lit pots of different sizes, inealis for cleaning the pot,

i'neans or'adjustiiig and setting the 'cleanlng means to' suit thc size of the particular the cleaning means. i

The particular form oli' my invention illuspot, and means forrotatinglor operating trated comprises inthe-supporting and fa'stoning inea-ns a plurality of supporting bars 12 which preferablyv extend radially from` and are fastened to a central dome or bracket 13' provided with an upwardly ex- Fig. Llis an elevational view of tlie-"operf ating mechanism, taken on line .4g-#4 of Fig. 1 and cutting the lifting lever, and

itending -sl1aped bracket 14 carrying a gearv housing-leon its upper end, said housingl thereto.` y 'llieidevicois supported by-bars A1 2 han@ 9."

fastenedoiiz'fsziid'pinandfis held in its liori- V .'zoiital `position incliai'nbe'r 1,9 'by' means of said ,upper-*plateflsgand 'tliclower parts of tion, A circular cover- 23, with a central-- opennwgfiittng "over 4.thinex-13, 'iis mounted von the upper plate 18,'.enga'giig beneath lip 17 of member 12,'and Ais provided with forwardlynndf outwardly extending slots 24 in which tbe-.tops -ofp`ins20 are arranged to slide.' Knobs 25 are fastened on said cover by means of which tlic cover may lie rotated in clockwise direction,A as indicated by the arrow in Fig. 2,-tliereby forcing the pins 20 inward in slots 24 and in theslots in bar 12, toward p tlie vcenter of said 'cover so as to clamp tlie ends 2l of said pins tightly under .tlie bead 11.- 'iliis cover arrangement will thus fit' or lhold iirinly on pots of variousdiainclers, within the limits of said slots. A

Wing nut 26 is preferably threaded on one of'said Vpins so that the cover elements may be locked firmly and positively'iii vposition on the pot. i

` The means for cleaning the pot comprises I a tube or member 28 journalled verticallyv in housing 15 and dome 13, and provided with two pairs of ears 29 pivoted 'to the upper ends of links .30 and 31, an angular lower-end of link 30, said brush being provided with 'a main horizontal portion for engaging the" bottom of thevpot and a verti-` -bri'islrl being p'ivoted in a jaw 34 at the of set screws 38, or in rany suitable manner,

and said bristles may consist of steel, hair,

or vegetable fibers, or the cleaning portions may be provided with mineral wool as steel 'Wool or aluminum wool,` instead of the bristle portions, likewise scraping or scouring members of stone or metal may be substituted for the usual removable -cleaning portions of the brushes where a pot contains firm sediment or incrustation.

, The means for adjusting and setting the cleaning mechanism comprises a shaft 39 which is adj ustably mounted in tube 28 and is held in position therein by means of a set screw 40. A cross bar 41 is mounted on the lower end of said shaft and contains a pair of jaws 42 and 43 for slidably engaging links 30 and 31 to move said links and their attached brushes transversely of the .pot to suit the diameter of said pot, and a spring 44 connects the lower parts of said links and holds them in said jaws. The brushes are also swingable on their pivots to adjust themselves automatically to the curvature or contour of the pot.

The means for operating the device comprises a gear 45 mounted on tube 2 8, as by means of a key and slot or-in a similar l manner, to rotate therewith and to slide longitudinally thereon. A suitable collar 46 is interposed between said gear and the upper journal part 47 of housing 15, and a gear 48 meshes with gear 45 and is fastened on a shaft 49 journalled in said housing, aliand crank 50 being fastened to the outer end of shaft 49 to operate said gears and rotate the cleaning means. A control lever 51 is pivoted on a bracket 52 on dome 13, and con-' tains a fork 53 engaging between flanges 54 and 54 provided on tube 28, to raise the tube and brushes inorder to wash the upper part of the pot 10 with the rotating brushes. The device will be made in Several sizes, and each size is adjustable within certain limits, that is, the cleaning mechanism within the pot as well as the covering and tastening mechanism on the pot are adjustable tq suit the various The smaller device for home or. kitchen use will preferably be driven by hand operated means, while the larger device for use with larger pots and vessels, as are used in hotels and the like, will pre'ff l sly be driven by power means, such as an electric motor or the like.

Vhile I have illustrated and described the preferred form of construction for carrying my invention into elect, this is capable of variation and modification witlioutdeparting from the spirit of the invention. I, therefore, do not wish `to be limited to the pi'ecise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

lHaving described my invention, what I claim as new and desire to secure by Letters Patent is: i
